Hepatitis B virus status and risk of pancreatic ductal adenocarcinoma: a case-control study from China.

Author information

Department of Gastroenterology, Changhai Hospital, Shanghai, China.



This study was to assess the role of hepatitis B virus (HBV) infection in pancreatic ductal adenocarcinoma (PDAC) risk using a hospital-based case-control design.


Patients with pathologically confirmed PDAC (943) and 1128 matched controls were recruited from 2 hospitals. We evaluated the associations between risk of PDAC and age, sex, history of diabetes mellitus (DM), etc. In addition, we examined the interactive effects of HBV status and known risk factors for pancreatic cancer.


Chronic hepatitis B and inactive hepatitis B surface antigen (HBsAg) carrier state (HBsAg positive) had a significantly increased risk of pancreatic cancer, with an adjusted odds ratio of 1.60 (95% confidence interval [CI], 1.15-2.24). Furthermore, significant interactions were detected between a history of DM and chronic hepatitis B and inactive HBsAg positive, but not with antibodies to hepatitis B core antigen (anti-HBc) positive/antibodies to HBsAg (anti-HBs) negative, with an adjusted odds ratio of 5.42 (95% CI, 2.76-10.64), compared with those who were HBsAg negative/anti-HBc negative without a history of DM.


These results suggest that HBsAg-positive or anti-HBc-positive/anti-HBs-negative patients have an increased risk for PDAC independent of other risk factors. Significant interactions were found between a history of DM and chronic HBV infection for PDAC risk.
